Summary
Wazuh : size_t underflow in msgs.c ReadSecMSG causes wazuh-remoted DoS and potential heap overflow via crafted agent message
Details

Wazuh is a free and open source platform used for threat prevention, detection, and response. In versions 3.0.0 and above, prior to 4.14.5, a size_t integer underflow in os_crypto/shared/msgs.c:389 allows any enrolled Wazuh agent to crash the wazuh-remoted process on the manager, immediately disconnecting all agents from the manager. A second code path reached by the same underflow may allow heap memory corruption. This issue has been fixed in version 4.14.5.
